Abstract
A universal closure for a dispenser is contemplated. The closure seals to the container neck along three separate surfaces with sufficient force to enable the use of lockdown and/or anti-rotational features to secure the dispenser for e-commerce shipments. Provision of frictional projections secures a sufficiently tight fit between the container neck and the body insert of the closure so as to eliminate the need to force separate engagement features on the container itself.
